Kifah Mustapha was appointed last December. But a blog pointed out that he had worked for a Muslim charity group, the Holy Land Foundation.

Several of its leaders have been federally convicted for funneling money to Hamas, a Palestinian group on the U.S. foreign terrorist list. But Mustapha himself was never indicted for anything.
Ahmed Rehab of the Council on American Islamic Relations says this is a smear campaign:

REHAB: And then government entities give into that fearmongering and Islamophobia and end up axing Muslim participation in our civic life.

The Illinois State Police won’t say what it found in Mustapha’s background check after his appointment. But it says it will find another Muslim chaplain.
